Evidence that I”S? Controls Interfacial Electron Transfer Dynamics from Anatase TiO2 to Molecular Acceptors

Recombination of electrons injected into TiO2 with molecular acceptors present at the interface represents an important loss mechanism in dye-sensitized water oxidation and electrical power generation. Herein, the kinetics for this interfacial electron transfer reaction to oxidized triphenylamine (TPA) acceptors was quantified over a 70 temperature range for para-methyl-TPA (Me-TPA) dissolved in acetonitrile solution, 4-[N,N-di(p-tolyl)amino]benzylphosphonic acid (a-TPA) anchored to the TiO2, and a TPA covalently bound to a ruthenium sensitizer, [Ru(tpy-C6H4-PO3H2)(tpy-TPA)]2+ “RuTPA”, where tpy is 2,2?:6?,2??-terpyridine. Activation energies extracted from an Arrhenius analysis were found to be 11 ¡À 1 kJ mol-1 for Me-TPA and 22 ¡À 1 kJ mol-1 for a-TPA, values that were insensitive to the identity of different sensitizers. Recombination to RuTPA+ proceeded with Ea = 27 ¡À 1 kJ mol-1 that decreased to 19 ¡À 1 kJ mol-1 when recombination occurred to an oxidized para-methoxy TPA (MeO-TPA) dissolved in CH3CN. Eyring analysis revealed a smaller entropy of activation |I”S?| when the a-TPA was anchored to the surface or covalently linked to the sensitizer, compared to that when Me-TPA was dissolved in CH3CN. In all cases, Eyring analysis provided large and negative I”S? values that point toward unfavorable entropic factors as the key contributor to the barrier that underlies the slow recombination kinetics that are generally observed at dye-sensitized TiO2 interfaces.

delta-Acidity of benzene in [(benzene)RuII(N-N)Cl]+. Crystal structures, nuclear magnetic resonance spectra and nucleus independent chemical shifts

The ligands L1 and L2 are 1:1 condensates of acetylacetone and 2-hydrazinopyridine and 2-hydrazinobenzothiazole respectively. Reactions of these ligands with [RuCl2(C6H6)]2 in 2:1 M proportions in the presence of excess NH4PF6 yield two complexes ? dark red [(C6H6)Ru(L1)Cl]PF6 (1) and yellow [(C6H6)Ru(L2)Cl]PF6 (2). Their X-ray crystal structures have been determined. They are 1:1 electrolytes in dimethylsulfoxide (dmso). The bonding in the complexes involves significant back donation from the filled dxy orbital of the metal to the empty pi? orbital of coordinated benzene, as confirmed by the visualization of the HOMOs in 1 and 2 obtained from the density functional theory (DFT) calculations. As a consequence, in the 1H NMR spectra in dmso-d6 the benzene protons are shifted to lower values of 6.23 (in 1) and 6.37 (in 2) from 7.26 ppm of the free benzene. Thus the protons of the ligated benzene become less deshielded compared to free benzene. Further a concomitant lengthening of the C?C bonds in the coordinated benzene by ?0.04 A is observed. A pseudo-octahedral geometry of Ru(II) in 1 and 2 is stipulated from a d-d transition which gives the 10 Dq value of 24,500 in 1 and 24,000 cm?1 in 2. The NICS(0) value, an index of aromaticity, calculated at the center of the benzene ring by GIAO method at BP86/LanL2DZ level, of ?6.53 ppm in free benzene becomes more negative in 1 (?20.36 ppm) and 2 (?21.45 ppm). Thus coordinated benzene becomes more aromatic from the point of view of NICS. In addition when NICS is varied as a function of the distance (up to 0.8 A) above the center of the benzene ring, it increases in complexes 1 and 2 whereas in unbound benzene it decreases.

Complexes [RuL(iPr-saloxaz)(mes)]Y (L = py, 2-Mepy, 4-Mepy; PPh3; Y- = SbF6 or BPh 4) 6-9 were prepared by treating the chloride 2a with ligand L and NaY (Y- = SbF6 or BPh4) in methanol at reflux. Halide complexes [RuX(iPr-saloxaz)-(mes)] (X = Br, 10; X = I, 11) were synthesised by treating 2a with AgSbF6 then with 1.2 equivalents of KBr or NaI, the methyl complex [RuMe(iPr-saloxaz)(mes)] 12 was synthesised from 2a by reaction with MeLi.

Efficient preparation of chiral non-racemic sulfur compounds

p-Menthane-3-carboxaldehyde serves as an efficient chiral auxiliary in the preparation of chiral non-racemic S-alkylthiocarbamates or 5-dithiocarbonates via the 3,3-sigmatropic rearrangement of the corresponding alkylthionocarbamates or xanthates. The transfer of chirality during rearrangement is complete, and the final products possess a chiral tertiary or quaternary carbon bearing sulfur. The rearranged products are then transformed into enantiopure cyclic or acyclic sulfur-containing products, depending on the means of clivage of the auxiliary. The synthesis of a potent MMP-13 inhibitor is presented.

Rational design of highly cytotoxic eta6-arene beta-diketiminato – Ruthenium complexes

A series of ruthenium-benzene complexes with beta-diketiminate ligands modified with electronwithdrawing groups were prepared and characterized by NMR spectroscopy, mass spectrometry, and single-crystal X-ray diffraction. The complexes are stable in air and undergo controlled hydrolysis in water. The complexes were evaluated for anticancer activity in vitro, and two of them proved to be highly cytotoxic, comparable or even superior to cisplatin. This work shows the potential utility of the betadiketiminate ligand in the rational design of new anticancer metal-containing drugs. A related complex with a eta6-C6H5CF3 ligand was prepared and found to undergo a nucleophilic addition reaction at the coordinated arene ring to afford a substituted eta5-cyclohexadienyl derivative.

Self-aggregation of amino-acidate half-sandwich ruthenium(II) complexes in solution: From monomers to nanoaggregates

The aggregation tendency of [RuCl(AA)(Arene)] complexes (1, AA = amino acidate = Gly, Arene = p-cymene; 2, AA = Ala, Arene = p-cymene; 3, AA = N,N?-dimethyl-Gly, Arene = benzene; 3b, AA = N,N?-dimethyl-Gly, Arene = p-cymene; 3c, AA = MAT-dimethyl-Gly, Arene = hexamethylbenzene; 4a, AA = t-Leu, Arene = benzene; 4b, AA = t-Leu, Arene = p-cymene; 4c, AA = t-Leu, Arene = hexamethylbenzene; 5, AA = alpha,alpha?-Me2-Gly, Arene = p-cymene; 6, AA = alpha,alpha?-Ph2-Gly, Arene = p-cymene; 7, AA = Pro, Arene = p-cymene) as a function of the concentration and solvent (CDCl3, CD2Cl2, acetone-d6, and 2-propanol-d8) was investigated through diffusion NMR measurements. The equilibrium constant (K) and the standard variation of the free energy (DeltaG) for the aggregation process were determined by applying the Equal K self-aggregation model. The highest level of aggregation was observed for complexes 1, 2, and 4, bearing the NH2 moiety, which was involved in intermolecular H-bonding. Complex 2 formed aggregates with a hydrodynamic radius (rH) equal to 20.8 A in CDCl3 (DeltaG296K == -7.1 ¡À 0.7 kcal mol-1) at a concentration of 124.9 mM, corresponding to an aggregation number (N) of 133. On the other hand, complex 3c did not show any tendency to aggregate (N = 1.1, 0.5 mM in CDCl3). The aggregation tendency decreased as the steric hindrance of arene (4a > 4b > 4c) and AA (1 ? 2 > 5 ? 4b > 6) and the polarity and proticity of the solvent increased. For complex 2, -DeltaG(kcal/mol) was 7.1 in CDCl3 (epsilonr = 4.81) > 5.6 in CD2Cl2 (epsilonr = 8.93) > 3.9 in acetone-d6 (epsilonr = 20.56) > 3.0 in 2-propanol-d8 (epsilonr = 19.92). While the two diastereoisomers of complexes 2 and 4b showed substantially the same tendency to self-aggregate, diastereoisomer (RRu, SN, S C)-7 showed a remarkably higher aggregation tendency than the other one [(SRu, SN, SC)-7] throughout the entire concentration range (1.4-178.0 mM) in CDCl3, indicating that a diastereoselective recognition process is occurring in solution [|Delta(DeltaG296K)| = 1.8 ¡À 0.5 kcal mol -1].
